Rajinder Khanna meeting Indian Prime Minister Narendra Modi
Khanna is considered the founder and driving force of the counter-terrorism unit in R&AW,[7] and he is said to be an expert on terrorism. He was appointed one of the three Deputy National Security Advisors of India in 2018, taking over from Arvind Gupta.[8] Khanna was the first R&AW chief who was directly recruited into R&AW cadre from the IPS.[9] Khanna served as the Deputy NSA in charge of Technology and Intelligence (T&I). He was appointed the first ever Additional NSA in Indian history in 2024. He has been a member of the National Security Council (NSC) because of both the positions he holds.[10] As the Deputy NSA, he played a key role in establishing the office of the National Cybersecurity Coordinator at the National Cyber Coordination Centre. The aim of this office was to create a centralized structure to combat cybercrime and cyberattacks.[11]
The office of the Additional NSA has always existed in the Indian security apparatus, but was never occupied by any official. In his first term in the NSC, Khanna worked along with the other two Deputy NSAs Vikram Misri and Pankaj Singh, working under NSA Ajit Doval. In his second term in the NSC, Khanna worked under Doval, with the three new Deputy NSAs T. V. Ravichandran, Pavan Kapoor and Anish Dayal Singh. Indian officials said Doval and Khanna were retained to ensure continuity of the national security structure.[16]
